AN α-IONOL DISACCHARIDE GLYCOSIDE FROM RASPBERRY FRUIT

Article abstract of DOI:10.1016/0031-9422(92)80359-M

From a methanolic extract of raspberry fruit the 9-O-α-L-arabinofuranosyl-(1->6)-β-D-glucopyranoside of (6R,9R)-α-ionol was isolated.Its structure was established on the basis of 1H and 13C NMR spectroscopy.The absolute configuration of the aglycone was determined by direct chiral analysis using MDGC-mass spectrometry as well as 1H NMR analysis of its (R)-(-)-α-phenylpropionic acid ester.
